Beyond the Cataract: Clinically Significant Urinary Pathology Detected During Preoperative Evaluation—A Case Series"

Background
Cataract surgery is one of the most frequently performed ophthalmic procedures. Preoperative assessment is primarily directed toward identifying systemic conditions that may influence perioperative safety. Abnormal urinary findings, particularly pyuria, may be encountered during preoperative evaluation. Although pyuria is nonspecific and does not by itself establish urinary tract infection, marked or persistent pyuria may occasionally be associated with significant underlying urinary tract pathology.
Methodology
This was a descriptive case series of three patients who were evaluated for cataract surgery and in whom significant pyuria was identified during preoperative assessment. The cases were selected because the urinary abnormality prompted further urological evaluation and led to identification of clinically significant urinary pathology. Patient demographic characteristics, urine microscopy findings, subsequent urological investigations, diagnoses, interventions, and the timing of subsequent cataract surgery were obtained from the available clinical records. No intervention was assigned by the investigators, and no control group was used. The findings were summarized descriptively without inferential statistical analysis because of the small sample size. The purpose of the case series was to describe clinically important diagnoses encountered after significant pyuria was detected, and not to estimate prevalence or establish a causal relationship between pyuria and urinary pathology
Conclusion
These cases highlight that significant pyuria detected during preoperative evaluation may occasionally be the first indication of clinically important urinary tract pathology. Pyuria should not be interpreted in isolation as evidence of urinary tract infection, nor should these three cases be taken to support universal urine screening before cataract surgery. Rather, when significant or unexplained pyuria is encountered, appropriate clinical correlation and, when indicated, urological evaluation may identify treatable pathology and facilitate safe subsequent surgery.
